No idea how this has existed in NOX for so long.
In coreapps/pyrt/pyglue.cc lines 187 and 204 call htons(). They should
be htonl().

Which NOX branch are you using? If the answer isn't destiny, please try
again with destiny.
If you ARE using destiny, are you on a 32 or a 64 bit machine?

Hi,
I have trouble using the python flow fetcher. I can successfully fetch
flows as long as the request doesn't contain uint32_t types on fields,
i.e. nw_src or nw_dst. No matter what values I use, only the first two
bytes will be non-zero. For example, if I construct the request like
this:
Flow_stats_request = {dpid: dpid_int, match: {in_port: inport,
nw_dst: ipstr_to_int(192.168.1.2), dl_type: 0x800}}
with wireshark I can see flow fetcher sending Stats Request with nw_dst
1.2.0.0. It would seem that some bit shifting is going on, although I'm
not sure if I'm using the flow fetcher correctly.
Can someone please tell me how to get it working properly or suggest how
I can fix it if it's a bug? Thanks.

Re: [nox-dev] Running NOX on VmWare
I don't think we have enough information to answer your question. Which ARP messages are you talking about? What machine are they coming from and what are they asking for? And what's your purpose here? Are you going to add more VMs and connect them to virtual ports on VM2? (As you've described it, you seem to have a switch that isn't switching anything.) -- Murphy On Sep 14, 2011, at 11:01 AM, Candy Floss wrote: I have created two virtual machines in VmWare server.

Re: [nox-dev] Running NOX on VmWare
The messages are coming from the virtual machine. The network is getting flooded and the machine goes down so I'm not able to capture what messages are getting generated. My purpose is to configure NOX and test it. For that I have configured one Virtual machine as NOX and the other as open switch in the VmWare server. I do not have a physical switch, I have configured one virtual machine as a Switch. I will be adding more VMs but first I want to establish a connection between switch and NOX.
